[Nix-dev] gfortran and does not know the path to the glibc.

[Nicolas Pierron]

Apparently the gfortan compiler does not know the path to the glibc, I
have tried to set LD_LIBRARY_PATH and LD_RUN_PATH without success.  As
display with the '-v' option the gcc compiler does know this path and
correctly link to the glibc for files like crt1.o.

Does anyone have an idea to solve this problem ?

I have tried to recompile gfortran with "langC = true" without success.

$ cat hw.f90

program HelloWorld
  write(*,*) "Hello World"
end program HelloWorld

$ gfortran -c hw.f90

$ gfortran -v hw.o -o hw
